To all whom z't may concern:

Be it known that'I' RICHARD BATTLE, a citizen of the United btates, and a residentof Okmulgee, in the county of- Okmulgee and State of Oklahoma, have made certain new and'useful Improvements in Devices for Attaching Electric-Light Fixtures to Outlet-Boxes, of which-the following is a specification.

' plate, as'shown in g.

able insulation may be interposed between This insulation 1s- My invention is an improvement in de.-.

vices for attaching electric light fixtures tooutlet boxes, and has -for. its objectto provideqa device of the character specified, so constructed thatthe fixture, asffor instance 'a light, fan, or the like,'may.-be readily re- Inovable for inspection, repair,.interchanging, cleaning and the like, and adapted for use on either ceiling-or side 'wall.

. In the drawings Figure 1 is a plan view of the base section;" Fig. 2is' a vertical section';'- a 'Figs. 3, 4, 5 and 6 are sectional views showing the application to various types of boxes} Fig. 7 is a of cap;

' Fig. 8 is a side View of the, same. In the embodiment ofthe invention shown in Figs. 1 and 2,,the box 1 which is .of usual construction has connected there with at one side a conduit 2 by means of the usual lock nut s'3, and the lead wires 4j plan view of another form 'and 5 extend into the box through the conduit in the-usual manner. .Tl1e base section of the connection indicated at 6 is of usual form, and is secured to .the bottom of the box by screws 7 which pass through the lat-- erallugs 8 on the, connection.

The mounting, section 9 of the connectionis supported bythe pipe connection 10, the. said connection19'being secured to a ring 11 which is threaded on to the end of the pipe 7 connection, the said ring forming an annular rib or-shoulder on the end of the .con-

motion, and the ring is of the same diameter- *as the mounting section 9.

The end of .t

this end or inclined surface is adapted to contact with a bevel on the inner end of the plug, as-shown inFi 's. 2,- 3 and 4, or on the i 5 and 6, and sultthese inclined surfaces. 7 shown at 13 in Fig. 2. These tapered sur- Figs. '2 and 3. threaded. for engagement by an ornamental threaded petticoat the plug is externally threaded for engage- 1is ring remote from the sec-=- tion 9 is beveled or inclined as shown, and Y faces of the ring and (plug insure the center-' ing of the 'fixture', an the plug as shown at plate to cover the connection.

' The plug 12 in Fig. 2 is threaded into a ox, the said nipple extending inwardly with respect to the cover.

nipple-l5 in the cover plate 16 of the outlet In F ig.'3 the cover plate 17 has an out ivardly extending externally threaded nipple l8,"wh1ch is engaged by an internally 19 on the plug 20, and

Inent by the ornamental plate" above mentioned- A 'pipe" connection 21- has the collar 22 threaded thereon which is adapted to be engaged by the inner end of the plug, the collar and plug having tapering surfaces for properly centering the mounting connection which is not shown in the present instance,-but'is connectedto the collar.

In Fig. 4 the cover plate has an outwardly extending internally threaded nipple 24, which is.engaged by the plug 25. The pipe connection 26 has the collar 27 threaded thereon, the engaging faces of the, collar and the plug'being tapered in the same. manner as shown -in' Figs. 2 and- 3'. The plug is externally threaded in the same manner as the plugs '12 and 20.

In F ig. 5 opening- 28 of the cover plate -29 through which the pipe connection 30 is to pass receives also-an. annular rib 31 on a plate 32, which. fits upon the cover plate and 'is'seoured thereto. The collar 33 correspond may be externally ing to the collar 11 of Fig. 2 is engaged by the rib 31- and this collar and rib having tapering engaglng faces. As shown the plates 29 and 32 have registering openings for receiving securing means.

In Fig. 6 the cover plate 34 has an open ing 35 which is of a diameter to permit the p'assage of the pipe connection 36, but which is smaller than the external diameter of the collar 37 threaded on to the tion. I

The inner ,wall of the opening 35 is beveled as shown to fit the taper of the collar the securing means. In this instance the collar is engaged directly by the plate M.

In Figs. 7 and 8, the plug 38. which is similar to the plug .12 of Fig. 2 instead of having threaded engagement with the cover pipe connecand the plate 34 has openings for receiving and the plug, cap or plate,

f it

l we ird plate, is held in place'by radial lugs 39. It will be noticed referring to Figs. 7 and 8, that the inner'end of this plug is beveled or tapered in the same manner as plug 12, and

for the" same purpose.

When hanging a fixture the connection 9,

supported by the mounting is thrust home as the case may be, is screwed up so that the fixture is held in place. Should the connections at any time become loosened they may be tightened by merely turning the plug.

I claim l. in combination with an outlet box hav-- ing a cover plate, a pipe connection, a plug and asectional electrlcal connection for. an electric lighting fixture, one of 831d sections being secured to the box and ,the other being i supported by the mountingfiior the fixture,

of a collar on the inner end of the pipe connection to which the section is connected, the

' plugharing' threaded engagement with the cover for the outlet box, and engaging the collar'at-i-ts inner end, said plug and collar having cooperating tapering engaging surfaces for the purpose specified.

2L In'combination With an outlet box hav'- ingca cover plate, a pipe connection, a plug and a sectional electrical connection for an electric lighting fixture, one of said sections being secured to the box and the other being supported bythe mounting for the fixture,

of a collaron the inner end of the pipe connection to which the sectionis connected, the

plug having threaded engagement With'the cover for the outlet'box," and engaging the collar at its inner end. 7

3. In combination with an'outlet box hav ing a coverplate, a pipe connection, a plug a the section and the insignia o,

and a sectional electrical connection for a light fixture, one section being secured to the box and the other being supported by the pipe, of a collar on the inner end'of the said connection to Which the'section is connected, the plug made rotatable on the pipe connection and having a detachable engagement With the cover plate and engaging the collar at its inner end, said connection being athreaded connection.

4. In combination With an outlet box hav-' ing 'a cover plate, a pipe connection, a plug and a sectionalelectrical connection for a light fixture, one section being secured to the vbox and the other being supported by the -pipe, of a collar on the inner-end of the said connection to which the section is connected, the plug made rotatable on the pipe connection and having a detachable engagement With the cover plate and engaging the collar at its inner end, the meeting ends of I plug being tapered to fit one Within the other. p I 5.
